From US Security Umbrella to European Autonomy: Are Nuclear Weapons the Solution?

The discussion in Europe regarding a new security architecture that includes nuclear deterrence is gaining increasing importance, especially in light of the questionable reliability of the US as an ally and nuclear threats from Russia.
At the Munich Security Conference, the 'European Nuclear Studies Group' presented a report highlighting the need for Europe to strengthen its nuclear deterrence in order to address potential future strategic failures.
German Christian Democrat Chancellor Friedrich Merz referred to talks with France on a possible 'European nuclear deterrent'. French President Emmanuel Macron is considering linking the French nuclear doctrine to the common security interests of key countries.
However, there are divisions, with some German politicians expressing reservations or emphasizing that the issue is not a priority. Others are concerned about the rise of the far right in Europe.
Europe is at a critical crossroads, with conflicting views on nuclear deterrence and the need for 'ethical rearmament', as proposed by Spanish Prime Minister Pedro Sánchez.
The 'European Nuclear Studies Group' report concludes that Europe faces 'bad choices' and that reliance on US nuclear deterrence remains the most reliable short-term solution, but Europeans need to consider alternatives.
